Application filed-July 29, 1325. Serial No. 46,754.

vadapted for use with resilient fillingunits such as springs or cushioning material.

As commonly made, a cushion cover consists of pieces of fabric, usually burlap, cut and sewn together not only to form the bottom, top and side walls, but a series of individual cells .or pockets within the outer walls, and adapted to contain the resilient material units. The problem of making cushion covers is not merely one of structure, but it is one of the methods of preparing the material for sewing, and then sewing' the pieces together, so that the cushion can be loaded with resilient material with the least amount of time and labor.

ln companion applications filed by'me. on the 18th and 24thdays of July, 1925, and bearing Serial Nos. 44,416 and 45,735, respectively, l have shown and described improved constructions of cushion cover and methods of manufacturing the same, includ.

ing the use of so-called combs or integral strips of material used for forming` certain side walls of individual compartments. In the present invention I provide an improved construction wherein similar combs form all the walls of the individual compartments beingincorporated in the completed cover with greater facility and less operating costs and also affording a lighter and more readily ventilated cover construction.

Of such a nature is the present invention, and its applicability to the art will be better appreciated as the process is disclosed with the aid of the accompanying drawings, in which- Figure l is a perspective view showing a portion of the material forming one of the covers, said material being marked off for subsequent sewing of partition strips along predetermined lines.

Figure 2 is a similar view of the piece shown in Figure l but illustrating an arrangement of combsasappliedv to thevmate- 'rial forming one of the covers to form a base.

Figure 3 is a perspective view ofthe top cover piece with the combs sewed thereto.

Figure 4 is a detailed view in vertical section of the complete assembled cushion, taken on line 4-4 of Figure 2.

Figure 5 is a view similar to Figure 4, but taken at` right angles thereto.

Figure 6 is a detailed view illustrating the method of manufacturing the combs before sewing into the structure.

Figure 7 is a detail view in vertical section of a modified formgof my invention.

Regarding first the structure of the cushion as a whole, a portion yof which is shown in Figures 4 and 5, thev same consists of top and bottompieces l and 2 of suitable fabric, such as burlap, sewn together at the edges in a seam 3l extending around the cushion vbetween the top and bottom thereof, the marginal portions of these pieces forming a boxing or end and side walls of the cushion. e

lVithin the outer covering formed by they pieces l and 2 are a series of continuous CFI combs extending the full length (or width) y of the kcushion with the longitudinal edges thereof sewn to the top and bottom cover pieces. These combs are parallel with each other and divide the interior space of the cushion into a plurality of full length compartinents. Each of these combs is made up of a base 4l and a plurality of tabs 4b connected therewith, said tabs extending the full height of the cushion, as will hereinfter appear.

In connection with the compartments formed between the combs 4 and arranged transversely thereof is )rovided a plurality of division walls 5 whic divide the cushion into a plurality of smaller compartments or cells. ln the finally completed cushion each of these division walls 5 is made up of two parts a sewn together adjacent their center in a seam 5b as will hereinafter appear. Each set of tabs 5ft-5a are part of oppositely disposed combs indicated generally by numerals 7 and 8 and arranged transversely ofthe combs 4 but each being of substantially one-half the height of the latter combs as shown in Figures 2 and 3. The lower combs 7 are attached to the bottom cover 2, as shown in Figure 2, transversely of the combs 4 while the upper combs lare attached to the upper covervl as shown inligure 3. The various steps taken in constructing the completed cushion wil now be described.

rThe first sten in the process is to provide a pair of similar top and bottom pieces l and 2 having sewing lines lll-l0 arranged at right angles to each other to outline the size of the compartments or cells of the complete/d cushion. To one of these pieces of material, as for instance, the bottom piece 2, as shown in Figure 2, is secured a set of combs l and T, each set being parallel to each other and arranged at right angles to the other set, as shown in Figure 2. es a nreferred method of construction of these combs, described and specifically claimed in my companion application executed July 17, i925, the combs e, and Sinay all be constructed in a similar manner, so that a description of one set of combs, as, for instance, the comb 7 will serve to illustrate the L. n. y construction or all. lhus, as shown in n ig ure 6, a single strip of material 9 is provided, being of a width substantially equal to the height cf one set of tabs 5 plus the height of two bases 7a. rThis strip is marked with two rows of sewing lines l2-12 parallel to and adjacent each side margin, and a second row ot sewing lines 5 is marked parallel to and spaced inwardly from the first named paill of sewing lines l2l2. rlhe strip is then cut along transverse lines 9 and longitudinal lines 9b so as to form two sets of combs, in which the width of each of the tabs 5 is the same as the notches 5b. rlhe cutting operation may be carried out in any suitable manner, as, for instance, by rotary cutting machines of the type well known in the art, which may be readily adapted for the purpose. rlhe combs formed as described, are then cut into suitable lengths and secured to their respective covers.

1n the case of the combs 7, the same is secure-'l to the cover 2 along sewing lines 12H12 fvneviously marked on the base 7* and cio-1 to the bottom margin of the notches 5" now formed therein. As will be seen from ure 2, an entire series of strips or combs re sewn in parallel relation along adja i sewing lines l() on tie base 2 in this manner, and a series of combs 8 are also se- ."zued to the cover l, it being understood ih at these combs are also made in pairs from a single piece of iaterial as already de- "bed in connection with the combs 7, but the tabs la thereof being substantially twice the height of the corresponding tabs 5 of combs 7. For the purposes of my invention, it makes little difference which set of combs and 7 are applied irst to the base piece 2. ln either case, the first set of combs, as in the present instance, the combs Y, are applied rectly to the base piece and then the secoiic. set of combs, in the present instance the combs 4, are then applied to the base 2 along seams 4C, these seams following the .ransverse sewing lines 10 and passing through the centers of aligned tabs of combs 7 as shown in Figure 2.

Referring now to the top piece l, a plurality of combs 8 of construction similar to the shorter combs 7 are arranged along parallel seams 13 to correspond with the similar combs 7 secured to the bottom cover 2. The arrangement is such that the top cover l with its combs S assembled thereon may be fitted over the bottom cover 2 with its combs T and e in position to be secured together in finally assembled form, as shown in Figures Ll and 5.

A preferred method of securing these parts may be described as follows:

Starting along one edge of the cushion parallel with the longer combs il, the cells or compartments are completed progressively in rows towards the opposite edge of the cushion substantially as follows: The iirst row of tabs YL- of the abutting combs 7 and 8 between the iirst comb 4: and the cushion edge are sewn together along sewing lines 5C which were previously marked on the continuous strip A. from which said combs were cut as hereinabove described. The free upper edges of the tabs lL-4b of the irst comb i are then sewn to the upper piece l along sewing lines C (previously marked in the same manner as sewing line 5 of comb 7) said sewing lines i? registering with the corresponding sewing lines 10-10 on the upper cover piece l, to complete the {irst row of cells.

rifhe assembling operation may then be continued as follows: rlhe second row of pairs of abutting tabs :YL-FrL adjacent the first comb el are joined alone' seams 5, and the second comb d is then sewn to the top cover 1 to complete the second row of compartments, and this operation is repeated until all of the compartments are formed. @ne or more of the side and end walls may be closed or boxed along seams Il at time in the process, although, of course, the cushion is not finally closed or boxed along all sides until the individual compartments are loaded with suitable resilient material, as will hereinafter be described.

@ne of the principal advantages of the construction above described, the provision of the combs e, 7, and 8 in such a manner that their bases may be each connected to their respect-ive covers in a single sewing operation. Furthermore, the pro fision for joining the tabs ,5a-5a adjacent the center of the cushion is preferable inasmuch as the covers l and 2 may be drawn together or flattened during the assembling operation in such a manner as to permit each pair of tabs 53h-5 to be folded outwardly and the other' unassembled parts folded back, so that said tabs project from the part of the cover already assembled and may thus be quickly sewn together along their' sewing lines 5U.

A further advantage of the construction herein described, is that the sides of all the partitions forming the compartments are skeletonized, being closed only adjacent the center lines of each compartment. The construction manifestly affords maximum economy in material and yet the connecting strips are fully wide enough for practical purposes, especially when each compartment is to be loaded with helical springs, the connesting strips between the adjacent compartments being arranged so as to retain the J springs in their proper place. Furthermore,

the separate compartments being open atk all four corners, the cushion is extremely iight and is readily ventilated through all portions thereof, and furthermore affords maximum flexibility that is desirable to rapid and convenient loading of the cushion with resilient material such as springs.

As a preferred meansv of loading the resilient springs comprising helical coils of wire in the separate compartments, an implement known as a loading tool is used in which a number of springs equivalent to the number constituting a single row, are held flatly compressed within the tool.v The tool is then inserted Vinto the open end of the cushion and along one side of each longitudinal compartment formed between successive partition strips Li, the tool being held so that the flattened springs pass through the openings between the partition strips and the adjacent edges of the tabs. It will be understood, however, that a cushion cover constructed in accordance with my invention may also be loaded with other resilient cushioning means.

A modified form of my invention utilizing a plurality of transversely disposed combs, is shown in Figure 7. In this case the combs 11i and 17, as applied to the base 2, correspond to the combs 4 and 7 in Figure 2 but in this instance the two sets of combs are of equal height and are both connected directly to the top piece 1. The process of assembling this form is substantially the same as that already described in connection with the preferred form excepting, of course, that no combs are initially attached to the upper piece 1.

As before explained, the process of assembling the cushion cover with partition strips consisting entirely of combs, results in a marked saving of time, labor and material in the manufacture of the cover, eliminating the sewing of a multitude of short seams, each of which may be a separate sewing operation.
